What is Async?

Async is the short form of “asynchronous.” It is a program technique that is used to execute tasks independently from the mail flow. This means the main program keeps running when the other specific tasks are performed in the background without disrupting the main program.

An example of this is when the main website page keeps running, and the additional elements of the website, including the videos or images, load in the background. This does not stop the page from being displayed. This feature saves time and improves the page speed. It helps with technical SEO and improves the user interface.
